At low pressures, van der Waals' equation is written as `(P+(a)/(V^(2)))V=RT`.The compressibility factor is then equal to:

A

`(1-(a)/(RTV))`

B

`(1-(RTV)/(a))`

C

`(1+(a)/(RTV))`

D

`(1+(RTV)/(a))`

Text Solution

Verified by Experts

The correct Answer is:
A
`(P +(a)/(V^(2)) (V) = RT rArr PV +(a)/(V) = RT rArr (PV)/(RT) = 1 - (a)/(VRT)`
